I've simply stopped taking any notice of sales prices, unless it is on something I buy regularly in which case I might bulk buy at the offer price. If I need/want something and there happens to be an offer somewhere, that is just a bonus. It may also alter where I buy it from (or exactly which it if there are similar products available for the same need). At the point where I'm parting with money what they think the item is worth means nothing to me and I won't be swayed by it – what matters is if the current price is good enough compared to how I value the item/service. Never let yourself think you will miss out be not getting a sale item now – it or something else will be at that price again in future. Closing down sales, especially online, are almost always something that sets my scammy sense a-tingling for various reasons. Always assume a special offer is not so special unless you have researched the market. If you don't have time to look into the details then it isn't that good an offer, and they are trying to rush you so you don't notice until you've paid. I may occasionally miss out on a genuinely good offer this way, perhaps on something I'll develop a true need for soon, but I'm sure this is incredibly rare. tl;dr: sales and marketing teams are, overall, lying scammy reprobates and should be treated with extreme suspicion unless you have unequivocal evidence that they are one of the very few “good ones”.
